How to calculate the breaking capacity(like 15ka,20ka) of
Circuit breaker (MCB,MCCB,ACB)
Answer Posted / sunil sethi
All are ok, but In industries generally 5MVA transformer they are using for a company load, then if we consider 5MVA is our load then Icu is 5/(1.732x440)=0.0065ka , please clarify, Is it ok please answer .

15hp motor wound by 0.9mm & 0.95mm magnet wire. at no load test it draw 4.2A current. Another motor with same condition draw 9.2A current. How can that occur? pls help
ii) A shunt motor supplied at 230V, runs at 900 rpm when the current is 30A. The resistance of the armature is 0.4 ohms. Calculate the resistance required in series with the armature to reduce the speed to 600 rpm, assuming that the armature current is then 20A. [12]
